VENTILATOR.

Specification of Letters Patent.

Application filed November 11, 1912.

Patented May 19, 1914. Serial No. 730,684.

To all whom it may concern:

Be it known that I, GEORGE C. Bunnnnrr, a citizen of the United States, residing at (lhicago, in the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

My invention relates to ventilators of the sort adapted to be placed on the outside of a car, building, or the like, and so coin strut-ted that drafts of air, naturally or artificially produced, bring about the exhaustion of the foul air from the space to he ventilated.

One of the principal objects of the invention is to provide a ventilator of this type which will be simple in its construction and cheap to manufacture, which will involve no movable or adjustable parts, and which, while utilizing the movement of the outside ir to the fullest xtent to cause the (Xhaustion of the impure air from the space to he ventilated, will not permit wind, rain, snow, dust and the like to blow or be forced or driven into the inclosed space through the openings in the ventilator.

Th-e invention has in view more particularly to provide a suitable ventilator for railway cars which may be placed either vertically over an opening in the roof of the car, or in horizontal position outside of a window or opening in the clear-story, when the car is of that type, and so constructed that it presents an air resisting surface in the direction of the movement of the car which is utilized to produce a suction through the ventilator that exhausts the foul air from the interior of the car.

The invention has for further objects the other new and improved constructions, arrangements and devices relating to ventilators to be hereinafter described and claimed.

The invention is illustrated, in certain typical eml'iodiments, in the accompanying drawings whcrein' Figure 1 is a view, in perspective, of one form of the invention. Fig. 2 is a sectional plan of the same. Fig. 3 is a vertical sectional view flllitll on the line 3-3 of Fig. 2. Fig. 4 is a sectional plan similar to Fig. 2 showing a slight modification.

Like characters of reference designate like parts in the several'figures of the drawings.

Referring first to Figs. 1 to 3 inclusive, the device may be said to consist of a boxlike structure mounted upon or provided with an annular base or neck 10. The boxlike structure is formed of an inner or lower plate ll formed with a central opening 12, an outer or upper end 13, preferably imperforate. forward and rear faces 14, and side walls 15, the side walls falling short of the forward and rear faces 1 so as to provide outlets 16 at the corners of the structure. \Vithin the structure are deflecting walls 17 preferably angular in cross section as best shown in Fig. 2, and provided centrally with openings 18 by means of which the inlet, through the base it). communicates with the outlet passages 19 formed between the deflecting walls 17 and the forward and rear faces 14. The faces 14: are preferably formed with the central bulging or V-shaped portions 20.

The device above described is used and -'operated in the following manner: It is placed either in the vertical position shown in the figures over an opening in the roof of the car, or else horizontally, that is, with one side wall 15 uppermost and the base or neck eonununicating with an opening or window of the clear-story of the car. In either position one of the faces 14 will ram the air as the car moves. This results in drafts of air of considerable velocity passing over the outlet openings 16 which produces a suction through the openings 18 and 12 which withdraws the foul air from the space to be ventilated. The faces l t are preferably arranged so that the air impinges thereon at right angles and has to make a right angle turn around their outer edges and'over the openings 16. In the construction shown, the center portions 20 of the faces 14 are bulged out into V-shape, primarily for the purpose of widening the exhaust passages 19 opposite the openings 18 so as to, prevent choking and back draft and also so as to deflect impinging air to ward the exhaust o 'ionings 16. The portions of the faces on opposite sides of the V-shaped portions are preferably flat and preferably stand at substantially right angles to the planes of the outlets 1G. The innor walls l7'arc given the angular config l uration so as to prevent the wind from blowing into the car through the openings 16 and 18. The V-shape of the faces 14: allows the air impinging against the portions of the wall 17 adjacent the openings 18 to sweep around said openings without choking the exhaust thercthrough. The side walls 15 are preferably concaved in order to give the air an outward sweep past the rear openings 10 although this is not essential. Obviously the device need not be provided with the base or neck 10. The configuration and proportions of the device may, of course, be changed as the circumstances of any particular installation require.

Fig. 4 shows a slight modification intended to he used particularly when the ventilator is placed in what has been termed the horizontal position. In this construction the deflecting walls 1'7 are formed above the openings 18 with projections or eaves 17*, the purpose of which is to deflect water, dirt, or other matter, and prevent the same from entering the car through the openings 18.

While I have described my'invent-ion in certain preferred embodiments, it wiil be readily understood that further modifications may be devised without departure from the principles of the invention.

I claim: 1. A ventilator of the character described, comprising a box having an inlet, imperforate faces having central bulging sections and lateral fiat sections extending therefrom, imperforate sides forming between them and said flat sections interposed outlet openings, and interior deflecting walls extending between said imperforate faces and connecting the'opposite sides at their, corresponding lateral edges to form with said sides a chamber within the box open to said inlet, s'aid walls being formed of members of angular cross-scction forming openings between them by which said outlet openings communicate through said chamber with said inlet.
